RAILWAY-COUPLING.

Specification of Letters Patent.

7 To all whom it may concern Be it known that we, CARL LEHNERT, aresident of Marselch, and HUBERT Hi'JLsEN-, BUsoH, a resident of Walsum,Germany, subj ects of the German Emperor, have invented new and usefulImprovements in Railway+ Couplings, of whichthe following is aspecification; I

This invention'relates to a coupling for railwaycars, the engagement ofwhich is automatically efleoted when two cars. abut against each other,while the disengagement can be done by hand from the side of the car.

The accompanying drawings show in Figure 1 in side view, and in Fig. 2in plan, the new railway-coupling as attached to the ends ofthecar.

The longitudinal rod (1 is supported in the base-frame of the car at band c in such a manner that it can move in its axial direction.

At the rear end projecting beyond the supporting-point b the rod (1carries a coil-spring d, intervening between the support I) and thecollar 6, in which the rod a terminates at this end.

I At the front end projecting beyond the sup porting-point c the rod acarries the fixed coupling member f, which is forked and has aninclinedabutting plane and a round inner surface. 1

Near the front end the rod a is provided with a movable coupling member9, the head of which is shaped round.

Below the base-frame of the car a transverse shaft h is movably mountedand provided with a fixed projecting rod i. The latter is at its freeend pivotally connected to a linkk, the free end of which is in turnpivotglly connected to the movable coupling memer g. The free ends ofthe transverse'shaft h projecting at the sides of the car are providedwith a fixed reversing-lever l, which is counterweighted in order tobalance the movable coupling member 9 when the latter is in itsdisengaged position. Of course each end of the car must be provided withthe coupling, as abovedescribed.

The operation of the coupling isas followsz movable coupling member ofone car runs up the incline of the fixed coupling member of the othercar and is then caught behind the forked end of the latter. The cars areagain uncoupled by simply reversing the lever l of the transverse shafth from the side of the car,

whereby the movable coupling member 9 is lifted out of the fixedcoupling member 7: through the medium of the lever system 'i I PatentedNov. 6, 1906.

and is then held in this lifted-up position by v the counterweight ofthe reversing-lever Z.

By forming the head of the movable coupling member, as well as the innersurface of the fixed coupling member, round the former is allowed ofhaving a certain play in the latter, so that the coupling is efficientlyprevented from breaking even when the train runs over sharp curves.Having fully. described our invention, what we claim, and desire .tosecure by Letters Patent, is I A coupling for each end of a railway-car,comprising in combination, a longitudinal rod a supported in thebase-frame of the car so as to be capable of axial movement; acoilspring (1 placed around the rear end projecting beyond the innersupport of said rod a, a collar 6 fixed to the inner end of said rod aand destined to keep said coil-spring din place a rigid coupling memberf fixed to the front end projecting beyond the outer support of said roda and provided with a forked end, an inclined abutting plane and a roundinner surface; a movable coupling member g pivoted to the front end ofsaid rod aand provided with a round head and adapted to catch with thelatter behind the forked end of said fixed coupling member f of theother-car; a transverse shaft h movably mounted below the base-frame ofthe car a fixed projecting rod i provided on said shaft h; a link ispivoted with one end to the free end of said projecting rod 4 andwiththe other endto said movable coupling member g," and a counterweightedreversing-lever I provided at each free end projecting at the sides ofthe ear, of i set our hands in the presence of two subscribsaid shaft hand adapted to lift said movable ing Witnesses. coupling member 9 out ofsaid fixed coupling CARL LEHNERT. member f of the other car and to holdit in HUBERT HULSENBUSCH. 5 this lifted-up position, substantially asde- Witnesses:
